What is the total ATP produced at the end of electron transport?
usually 34-38
What is the four main steps of cellular respiration?
There are four main steps in cellular respiration are glycolysis, Link Reaction, Krebs Cycle and Hydrogen Transport Chain.In glycolysis, glucose molecules are broken down into pyruvate and pyruvic acid. Two molecules of ATP are produced in this cycle. This is fed into a link reaction, where some chemical rearrangement occurs.The Krebs cycle, also called the Citric acid cycle, allows extensive rearrangement of the atoms to occur. 2 molecules of ATP are produced in this cycle, bringing the total to four so far. Carbon dioxide is released as a byproduct, while the hydrogen atom is passed on to the next cycle.The hydrogen transport chain, also called the electron transport chain, is the last step of cellular respiration. In this phase, the electron belonging to the hydrogen is passed along a chain of receptors, with oxygen as the final receptor. The hydrogen atom is not used up in the reaction. This step provides the most ATP, with 32 molecules being produced.
What is the total number of ATP molecules formed during celluar respiration?
well the electron transport chain creates 34 ATP and the krebs cycle produces 2 ATP. but in the beginning of glycolysis 2 ATP is produced to 2 ADP then 2 ADP is produced to 4 ATP but then the shuffle step uses the 2 ATP.
How many ATP are produced from acetyl Co A that goes through the electron transport system?
Each acetyl CoA that goes through the citric acid cycle produces 2 Carbon Dioxide, 3 Hydrogen ions, 3 NADH, and 1 FADH2. The chemical components of this reaction are then able to create 1 ATP via substrate level phosphorlyation in the Electron Transport Chain. More importantly however, each NADH makes 3 ATP and each NADH2 makes 2, so combined, the 3 NADH and 1 FADH2 produce 11 ATP, or 12 when combined with the one from substrate-level. Since there are 2 acetyl-CoA produced per glucose during glycolysis, a total of 24 ATP is made during the electron transport system, as opposed to 36 or 38 for all of cellular respiration. However, all of these numbers are just theoretical. Slight imperfections and inefficiencies prevent most cells from ever actually achieving 100% of they yield as described. As a result, the total effective yield is closer to 28-30 for the overall process and only 9 or 10 ATP are actually produced per acetyl-CoA in the electron transport system.
The Krebs cycle and electron transport chain can produce a total of ATP?
Aerobic respiration (using oxygen) is a high energy yielding process. During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules.

How many protons in total are pumped into the intermembrane space of a mitochondria through the electron transport chain, if each complex individually receives 2 electrons?
12 protons
What is the purpose of the phosphorylation of glucose in glycolysis?
This creates a phosphorylated intermediate. Phosphates have high energy bonds, and typically make molecules more reactive. This phosphorylation makes the glucose more reactive.
How many ATP molecules are produced by the electron transport chain by glycolysis?
A net of two ATP are produced during glycolysis.
How many NADH molecules are produced in glycolysis?
There are 2 net ATP produced during glycolysis. 4 are produced but 2 are used so the net production is 2. There are 2 NADH produced which are then transferred to to the electron transport chain.

How many ATP molecules are generated for one molecule of glucose?
After glycolysis (the splitting of one glucose molecule, first step in cellular respiration in the mitochondria of a cell) the Krebs cycle, and going through the electron transport chain and ATP synthase...one glucose molecule can yield 38 ATP molecules.
